Too many files

[dholbrook86]

I will have notifications up and running for a few days or hours but then suddenly there are a whole mess of errors that require me to restart my entire docker deployment of 5 containers. I've taken a look at the container logs for RocketChatMobilePushGateway and have this ongoing repeating error:

I've tried viewing my socket limit with this command `cat /proc/sys/fs/file-max` on the host machine and inside the container itself. The limit is 760569 which seems high and fine.

What's going on? I really don't want to have to restart my containers every day.
